Baseball bat

ABSTRACT

This utility model discloses a type of baseball bat that falls within the baseball paraphernalia and is composed of a hitting part and a handle part; the inside of the hitting part is a hollow cavity, and the hitting—part wall body is of unequal wall-thickness construction. Different sections of the hitting part may hit the baseball when hitting. The wall body of hitting part is of an unequal wall-thickness construction, therefore, different resilience effect may be achieved by the hitting part with different wall thickness, the hitting effect of each stroke is different, and the pitch of baseball achieved by baseball bat makes it hard for an attacker to catch the baseball.

BACKGROUND OF THE INVENTION

This utility model involves the field of baseball paraphernalia, particularly involves a kind of baseball bat.

Baseball is a type of ball game with high collectivity and opposability, mainly characterized by bat hitting. It is highly popular and has great influence in the world, known as “the combination of athletics and wisdom”. Baseball players are divided into attackers and defenders, and they play baseball in a sectorial baseball field using baseball bats and gloves. Baseball bat is a baseball paraphernalia usually used by defender to hit the baseball pitched by the attacker. However, the hitting-part wall body of a conventional baseball bat is of equal wall-thickness construction, the hitting effect achieved by any section of the hitting part is the same, the baseball flying pitch may be unlikely changed, and the baseball can be easily caught by the attacker.

BRIEF SUMMARY OF THE INVENTION

In order to solve the above problems, the utility model offers a kind of baseball bat whose hitting part is of unequal wall-thickness construction, with different hitting effects by hitting the baseball in different sections of the hitting part.

The technical solution for the new utility model: a type of baseball bat comprising a hitting part and a handle part; with a hollow-cavity inside the hitting part, characterized in that the wall body of the hitting part is of an unequal wall-thickness construction.

In the above technical solution, the cross-section of hollow cavity inside the hitting part is elliptic, polygonal or irregular.

In the above technical solution, the hitting part is fitted with a sheathcoat that may be changed as required to achieve different hitting effect.

In the above technical solution, the hitting part and handle part may be of one-piece construction.

In the above technical solution, the hitting part and handle part also may not be of a one-piece construction; the front end of the handle part is fitted with a connecting shaft, and the hitting part is interference-fit connected to the connecting shaft such that the hitting part may be connected to the front end of the handle part.

In the above technical solution, the connection of connecting shaft and hitting part is also reinforced with adhesive.

Compared with the prior art, the utility model has the beneficial effects are that different section of the hitting part may hit the baseball when hitting. The wall body of hitting part is of an unequal wall-thickness construction, therefore, different resilience effect may be achieved by the hitting part with different wall thickness, the hitting effect of each stroke is different, and the pitch of baseball achieved by baseball bat makes it hard for an attacker to catch the baseball.

DETAILED DESCRIPTION OF THE INVENTION

The following embodiments of the invention in conjunction with the accompanying drawings are clearly and completely described.

Embodiment 1

Drawing 1 shows schematically a kind of baseball bat embodiment based on the utility model.

This kind of baseball bat is composed of hitting part (1) and handle part (2), and the hitting part (1) and handle part (2) may be of one-piece construction. The inside of hitting part (1) is a hollow cavity (11), the cross-section of the hollow cavity (11) inside the hitting part (1) is elliptic, polygonal or irregular. Since the outer contour of hitting part (1) is cylindrical and the hollow cavity (11) is elliptic, polygonal or irregular, the wall body thickness around the hitting part (1) is inconsistent, and the wall body of the hitting part (1) is of an inequal wall-thickness construction.

Embodiment 2

Drawing 2 shows schematically a kind of baseball bat embodiment based on the utility model.

This kind of baseball bat is composed of a hitting part (1) and a handle part (2), and the hitting part (1) and handle part (2) may be of one-piece construction. The inside of the hitting part (1) is a hollow cavity (11), and the hollow cavity (11) of the hitting part (1) is elliptic, polygonal or irregular. Since the outer contour of the hitting part (1) is cylindrical and the hollow cavity (11) is elliptic, polygonal or irregular, the wall body thickness around the hitting part (1) is inconsistent. The wall body of the hitting part (1) is of inequal wall-thickness construction. The hitting part (1) is fitted with a sheathcoat (12) that may be changed as required to achieve different hitting effect.

Embodiment 3

Drawing 3 shows schematically a kind of baseball bat embodiment based on the utility model.

This kind of baseball bar is composed of a hitting part (1) and a handle part (2); the hitting part (1) and handle part (2) also may not be of one-piece construction; the front end of the handle part (2) is fitted with a connecting shaft (21), and the hitting part (1) is interference-fit connected to the connecting shaft (21) such that the hitting part (1) is fitted to the front end of the handle part (2); The inside of the hitting part (1) is a hollow cavity (11), and the hollow cavity (11) of the hitting part (1) is elliptic, polygonal or irregular. Since the outer contour of the hitting part (1) is cylindrical and the hollow cavity (11) is elliptic, polygonal or irregular, the wall body thickness around the hitting part (1) is inconsistent; the wall body thickness around the hitting part (1) is of inequal wall-thickness construction.

Embodiment 4

Drawing 4 shows schematically a kind of baseball bat embodiment based on the utility model.

This kind of baseball bat is composed of a hitting part (1) and a handle part (2); the hitting part (1) and handle part (2) also may not be of one-piece construction; the front end of the handle part (2) is fitted with a connecting shaft (21), and the hitting part (1) is interference-fit connected to the connecting shaft (21) such that the hitting part (1) is fitted to the front end of the handle part (2); The inside of the hitting part (1) is a hollow cavity (11), and the hollow cavity (11) of the hitting part (1) is elliptic, polygonal or irregular. Since the outer contour of the hitting part (1) is cylindrical and the hollow cavity (11) is elliptic, polygonal or irregular, the wall body thickness around the hitting part (1) is inconsistent; the wall body of the hitting part (1) is of inequal wall-thickness construction. The hitting part (1) is fitted with a sheathcoat (12) that may be changed as required to achieve different hitting effect.
